The short version. Focus Lock doesn't have accounts, doesn't track you, and doesn't send your blocklist, schedule, or PIN anywhere. Everything you configure lives only in your own browser. The one exception is handling payment for the one-time unlock, described below.
Everything Focus Lock stores lives in chrome.storage.local, a storage area private to this extension, on this device, in this browser profile. It is never uploaded anywhere by Focus Lock itself. Specifically, that's:
None of this is encrypted beyond whatever Chrome's own profile storage provides, and none of it is synced to a Google account or anywhere else by Focus Lock. Uninstalling the extension deletes it, per Chrome's normal extension-storage behavior.
When you add a site to your blocklist, Chrome asks (per site, via its own standard permission prompt) whether Focus Lock may access that site. This is entirely optional, and Chrome, not Focus Lock, controls when and how it's asked. If you allow it, that site's permission is used for exactly one thing: redirecting the browser tab to Focus Lock's own block page instead of loading the site. Focus Lock never reads that site's page content, cookies, or any data on it. The permission only lets the extension's blocking rule fire a redirect before the page loads at all.
If you decline, or never get asked because your browser doesn't offer it, the site is still blocked. Chrome simply shows its own generic "site blocked" error page instead of Focus Lock's. Removing a site from your blocklist also removes the corresponding permission, once no other profile still uses that domain.
The one-time paid unlock is sold and licensed through Lemon Squeezy, a third-party merchant of record (they, not Focus Lock or its developer, are responsible for collecting and remitting VAT/sales tax on the purchase). Focus Lock talks to Lemon Squeezy's public License API directly, with no backend server of ours in between, to:
Your license key and instance id are sent to Lemon Squeezy's servers only during these activate, validate, and deactivate calls. Nothing else about your device or usage is sent. When you buy, Lemon Squeezy (and its payment processing) handle your payment details and, if you provide one, your email address for a receipt and license-key delivery. Focus Lock never sees or stores your card details; that flow happens entirely inside Lemon Squeezy's own hosted checkout page, outside this extension. Focus Lock only ever stores back from these calls: your license key, the instance id, and whether the license is currently active, cached locally as described above. See Lemon Squeezy's own privacy policy for how they handle payment and license data.
If you never open the buy or activate flow, Focus Lock never talks to Lemon Squeezy's servers at all. The free tier works entirely offline, with nothing leaving your device.
If this policy changes, the update will ship with a new version of the extension and an updated "Last updated" date at the top of this page.
This is a small, single-developer extension with no support inbox beyond the feedback link on the Chrome Web Store listing. There's no data-request or account-deletion process to run, because there's no server holding your data to begin with. Clearing it is as simple as removing the extension or clearing its storage from chrome://extensions.

Focus Lock's one-time unlock is a single, non-subscription digital purchase (currently priced in the €9–15 range; see the Chrome Web Store listing for the exact current price). This section explains what you're entitled to, and what you'll get in practice, in plain language.
If you're unhappy with the paid unlock for any reason, ask for a refund within 14 days of paying and you'll get one, in full, no argument. Read below for why, and how.
If you're an EU (or otherwise EU-consumer-protection-covered) buyer, the Consumer Rights Directive normally gives you a 14-day right to withdraw from an online purchase and get a full refund, no reason required.
For purely digital content delivered immediately, like Focus Lock's unlock, which activates the moment payment succeeds, a seller can ask you to explicitly agree, at checkout, that you want access right away and that doing so means you give up that 14-day right. Whether that specific consent step appears on the checkout screen depends on how the payment page (run by our merchant of record, Lemon Squeezy) is configured, and that has not been independently verified for every checkout path as of this writing.
Rather than relying on that legal detail, Focus Lock's actual policy is simpler and more generous than the legal minimum either way: a full refund on request within 14 days of payment, no questions asked, whether or not you were shown that consent step. This avoids the whole question of whether withdrawal rights were technically waived, and it's the right thing to do for a €9–15 purchase.
Refund requests made after 14 days are handled case by case, for example a clear technical fault that made the paid features unusable. There's no subscription to cancel (it's one payment, once), so there's nothing recurring to stop.
Use the feedback link on the Chrome Web Store listing page, or reply to your payment receipt email from Lemon Squeezy, and say you'd like a refund. Include the email address you paid with so the payment can be found. Lemon Squeezy is the merchant of record for this purchase and processes refunds; they're issued back to your original payment method, typically within a few business days of the request being processed.
